In this paper, we propose a QRS complex detector based on the Mallat and Hwang singularity analysis algorithm which uses dyadic wavelet transform. We design a spline wavelet that is suitable for QRS detection. The scales of this decomposition are chosen based on the spectral characteristics of electrocardiogram records. By proceeding with the multiscale analysis we can find the location of a rapid...
In theory, the optimal strategy for all kinds of games against an intelligent opponent is the Minimax strategy. Minimax assumes a perfectly rational opponent, who also takes optimal actions. However, in practice, most human opponents depart from rationality. In this case, the best move at any given step may not be one that is indicated by Minimax and an algorithm that takes into consideration human...
In this paper, load balancing mechanisms in a parallel algorithm of vascular network development are investigated. The main attention is focused on the perfusion process (connection of new cells to vascular trees) as it is the most time demanding part of the vascular algorithm. We propose several techniques that aim at balancing load among processors, decreasing their idle time and reducing the communication...
Simulation and analysis of sophisticated systems require much computations. Moore’s law, although still allows for increasing number of transistors on the die, does not lead to increase of performance of single chip — instead it leads to increased parallelism of entire system. This allows for improving performance of those algorithms that can be parallelised; recurrence plot is one of such algorithms...
The aim of the paper is to extend our formal model of persuasion with an aspect of change of uncertainty interpreted probabilistically. The general goal of our research is to apply this model to design a logic and a software tool that allow for verification of persuasive multi-agent systems (MAS). To develop such a model, we analyze and then adopt the Probabilistic Dynamic Epistemic Logic introduced...
In this article a new modification of the well known segmentation technique, namely active contour - snake, was proposed. This modification consists in a new formulation of its external force based on the electrostatics. However the base idea of giving electric charges to the image and the snake has been already presented in several works, none of them clearly adressed the problem where the charged...
